This invention relates to a stool structure and pertains particularly toan improved means of securing supporting legs to a top member.

The primary object of this invention is to provide a cast articledesigned to be secured to the under side a stool seat and to receive theends of legs for the support of the seat in such a manner that readyreplacement of any one of the legs may be quickly made without employingnails, screws or other securing devices.

he invention broadly contemplates the provision of a casting consistinof a number of connected arms at the free end of each of which a legreceiving socket is formed, the arms being designed to be secured to theunder face of a seat body to dispose the sockets in the proper positionsfor the reception of leg members.

The invention will be best understood from a consideration of thefollowing detailed description taken in connection with the accompanyingdrawing forming a part of the present invention with the understanding,however, that the invention is not confined to any strict conformitywith the showing of the drawing but may be changed or modified so longas such changes or modifications mark no material departure from thesalient features of the invention as expressed in the appended claims.

In the drawing Figure 1 is a side elevational view of a stool equippedwith the casting device embodying the present invention;

Figure 2 is a sectional view taken substantially upon the line 22 ofFigure 1;

Figure 3 is aplan view of the casting per numeral 4, with their uppersurfaces in the same plane so that firm contact will be made therewith.The central portion of the body after the casting operation is bored asindi-' cated at 5 to receive the bolt 6 which is extended through theseat body 4 and which receives upon its lower end the nut 7 which bearsagainst the under side of the casting.

While the present article may be made for use in connection with fourlegged seats or chairs it is shown as designed for the construction ofthree legged stools. In order to arrange the legs 8 of the stool at theproper inclination with respect to the seat 4 the socket sleeves 3 aresuitably angularly directed from the ends of the arms so that when thecasting is secured to the under side of the seat body in the mannerdescribed and the legs 8 inserted into the sockets they will be properlyangled to support the stool in the correct manner.

In order to firmly hold the stool legs in I their respective sockets theinner wall of each socket is provided with a series of inwardlyprojecting wedges 9 each of which is of gradually decreasing height fromthe top to the lower end thereof where it merges into the wall of thesocket as indicated at 10] In this manner when a stool leg is driveninto the socket the wedges 9 will gradually cut into the face of the legand bind the same in the socket holding it against turning orlongitudinal movement.

From the foregoing description it will be readily seen that the articleherein described when employed in the construction of stools, chairs orother leg supported structures will enable the constructor to morequickly produce a finished article, will give a stronger finishedarticle than is obtained by securing the legs directly in the seat bodyand will enable the owner of the article to easily replace any leg whichmight become brokenso that the active life of the article will begreatly lengthened.

Having thus described my invention what I claim is 1. A casting for usein connection with leg supported articles comprising a body portiondesigned to be secured to the under side you of the article, including aplurality of radially arranged arms, a sleeve formed at the outer end ofeach arm providing a socket for the reception of a supporting leg, saidsleeves having a plurality of Wedges formed upon and extendingsubstantially the length of the inner Walls thereof for cutting into andholding a leg forced thereinto, said sleeves being arranged inconvergent relation and having the arms extending from and flush withthe upper or convergent ends thereof.

2. A casting for use in connection With leg supported articlescomprising a spider body portion having a plurality of radially arrangedarms, a plurality of converging sleeve members secured to said arms atthe outer ends thereof and integrally formed therewith, and a pluralityof tapering wedge 20 shaped leg securing members carried by saidsleeves.

In testimony whereof I hereunto afiix my signature.

PAUL A. RENNACK.
